   • Organizational Development Development of Information Systems Formation of Corporation

2. Basics of Workflow Management

   • Workflow Managment Systems don't really have a theoretical foundation, they are more practically oriented
   • Activities
     • Support of returning, formal, predictable events
     • Decomposition of operations in activities
   • Productive
   • Collaboration
   • Administrative
   • Ad hoc
   • Phases of WFM
     • Modeling
     • Evaluation
     • Execution
   • Tasks
     • Execution and control of WF
     • modeling of WF
     • Simulation of WF

3. Elements of WFMS

   • Controller, program manager, role resolution, notification, synchronization, data manager, history manager, causality manager
   • Generic implementation model
   • Types of Workflow Tools
     • Form Processors
     • Line-of-Business App
     • Mainframe and Legacy App

4. Modeling of Workflows

   • Levels of Modeling
     • Modeling of Activities Modeling of actors Modeling of dependencies Modeling of causalities
   • Process modeling
   • structural modeling
   • Jablonski - Terms
     • abstract level: rules are defined concrete level: models how to do
   • 4 layer model
     • process modeling requires several modeling levels
   • Normative language approach
     • developer and user speak different languages. Gap should be closed trough a language which is defined by vocabulary and grammar
     • Sequence
     • Conditional Branching
     • Unconditional Branching
   • Workflow Management Coalition
     • set up general model how to define business processes to be able to execute them as workflows
     • Meta process model
   • Semi-formal language
     • can't be automatically converted to computer language
   • Formal language
     • Petri Nets
